Application December 11, 1944, Serial No. 567,665

2 Claims. I l

The present invention relates to a metal tearing strip container or can having an interior collar arranged inside of the tearing strip and has particular reference to an improved construction of container of this type which has a lined reclosure cover within the sealed container having threaded engagement with the collar when enclosed within the can, such a cover being made eflective for hermetically reclosing the opened container after removal of the tearing strip in opening the container.

An object of the present invention is the provision of an interior collar tearing strip can wherein a-reclosure cover has threaded engagement with the collar and within the sealed can, the opening of the can by removal of the tearing strip releasing the reclosure cover for use in reclosing the can.

Another object of the invention is the provision of a hermetic air tight tearing strip can having a collar hermetically secured to the body wall, the collar providing a threaded seat for a reclosure cover confined completely within the can, such a cover being made effective for hermetically reclosing the opened can after the removal of the tearing strip in opening the same.

Numerous other objectsand advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a perspective view of a tearing strip container embodying the present invention;

Fig. 2 is an enlarged sectional view taken substantially along the section lines 22, Fig. l, and illustrating the can parts in their initial condition with a reclosure cover confined within the sealed can; and

Fig. 3 is a view similar to Fig. 2 but of the opened can after the tearing strip has been removed and the initial can cover has been discarded, the view showing the reclosure cover in its air-tight reclosing position.

The present invention. embodies a container having a body H and end closures l2 secured thereto in double seams l3. The usual sealing gasket or compound lining I4 is used in the seams l3 to make the same hermetic.

An interior collar l5 islocated inside of the body ll adjacent the upper end of the body, adjoining collar and body beads l6, l1 (Fig. 2) becollar and the body connection is also made as an air-tight joint and for this purpose the body scored with a pair of parallel score lines which include a lower score line 2| and an upper score line 22 setting off a tearing strip 23. At the side seam of the container, the tearing strip terminates in a tongue 24 which provides for engagement of the usual opening key. The two s'core lines 2|, 22 preferably are cut on the interior wall of the body in the usual manner.

The collar l5 at the lower score line 2| is formed with an inwardly and upwardly extending double rounded corner 25 which merges into a vertical wall 26 spaced inwardly from the body wall II and of a smaller diameter. At the top the interior wall 26 terminates in an inwardly extending reclosure curl 21 which provides a smooth mouth for the opened container. The body wall H above the upper score line extends into the upper double seam l3, this portion of the body wall being designated by the numeral 3 l,

A reclosure cover 35 is contained within the can and is of such construction as to be lightly carried on the interior collar- 3 when the can is sealed initially but is made usable as a reclosure member when the container is openedv by removal of the tearing strip 23. This cover has a cylindrical skirt 36 which terminates in an outwardly extending edge curl 31 at the bottom. The diamclined conical wall 43. At the inside and at the top the conical wall 43 extends by a gentlycurved corner 44 into a central panel 45, Preferably the plane of the central panel 45 passes through the top of the arched section 38 so that the cover 35 constitutes in effect a flush cover. Cooperating threads 48, 49 are formed respectively in the collar wall 26 and in the cover skirt 3 6.

A sealing gasket 5| is disposed in the annular groove formed on the under side of the arched cover wall portion 38, At the time the can is ready to be initially closed by seaming of the top end l2, the reclosure cover is loosely applied to onto the can and it is fully sealed (as in Fig, 2)

there is no danger of the enclosed reclosure cover 35 becoming unscrewed even 'though it is only loosely applied as the cover l2 prevents such displacement.

Upon removal of the tearing strip 23, the top cover l2 together with the detached body wall 3| may be thrown away as no longer of service. The can then may be fully opened by unscrewing the reclosure cover 35. The opened container thereafter may be hermetically sealed as often as desired merely by threadedly engaging the cover and the collar threads and rotating the cover. By screwing down tightly, the gasket 5| is caused to press down against the collar curl 21 so that the curl becomes embedded in the gasinvention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

Iclaim:

1. In an air-tight sheet metal container ca pable of air-tight reclosure, a container bodyhav- 'ing score lines defining a removable tearing strip for opening the container, end closures for sealing the opposite ends of said body, a collar located inside of said body and hermetically secured at its inner end thereto, the upper part of said collar being spaced inwardly from said tearing strip, said collar having an upper portion extending inwardly and thence upwardly to provide a cylindrical wall terminating-at the top in a reclosure c'url, a separate rotatable reclosure cover seated on said collar and disposed entirely within said container and said top end closure, said cover having a depending cylindrical skirt and an inwardly spaced annular reclosure gasket channel, a sealing gasket in said cover channel for engagement with said collar curl, and interengaging means on the cylindrical wall of said collar and on the cylindrical skirt of said reclosure cover for drawing said reclosure cover into an air-tight seal with said collar by embedding said collar curl into said reclosure cover gasket, the

removal of said tearing strip to open the con-' tainer permitting the hermetic reclosing of the opened container by said reclosure cover,

2. In an air-tight sheet metal container capable of air-tight reclosure, a container body having score lines defining a removable tearing strip for opening the container, top and bottom end closures for sealing the opposite ends of said body, a collar located inside of said body adjacent said tearing strip and hermetically headed at its inner end into said body in anv air-tight seal, said collar'extending inwardly to provide a cylindrical wall terminating in a reclosure curl spaced inwardly from the body wall, a separate rotatable reclosure cover seated on said collar and entirely confined within the sealed container and disposed beneath said top end closure, said cover having a vertically disposed depending cylindrical wall fitting outside of the cylindrical wall of said collar, a sealing gasket in said reclosure cover in .vertically disposed alignment with said collar curl, and cooperating threads in the cylindrical walls of said collar and said reclosure cover respectively, said threads being rendered operative by removal of said tearingstrip and said top end closure to open the container, to form an airtight seal'between said reclosure cover and said collar by drawing the reclosure cover gasket tightly in embedded engagament against the re closure curl of said collar, thereby again hermetically sealing the container for reclosure pur- I poses.
